Dell PowerEdge R640 4LFF Server

The Dell PowerEdge R640 is a 1U rack-mount server system with a 4-bay 3.5-inch drive chassis. It ships with one Intel Xeon Silver 4215R processor running at 3.2 GHz and 64 GB of DDR4 ECC registered memory. A PERC H740P RAID controller and dual 750 W power supplies are installed. No hard drives are included.

Suits virtualisation hosts needing dense 3.5-inch

This configuration fits workloads that require up to four large-form-factor SATA drives and a single 8-core CPU with 11 MB cache. iDRAC9 Enterprise remote management is licensed. Buyers who need a second processor, more than four drive bays, GPU acceleration, or storage interfaces beyond SATA should evaluate other platforms.

The 4-bay 3.5-inch chassis limits internal capacity

Only four 3.5-inch SATA drives can be installed directly in this chassis. Expansion beyond that requires external enclosures. If your deployment needs more internal bays or a different drive form factor, this specific R640 model will not meet the requirement.

Questions about this item

What rack depth and height does the 36 x 24 x 10 in chassis need for a standard 4-post mount?

The 36 in depth and 10 in height fit a typical 42U rack; allow at least 36 in of usable rail depth and 2U of vertical space for the 4LFF chassis.

How is the PERC H740P controller seated, and what step is often missed?

The controller slides into the dedicated internal storage slot until the latch clicks; the step often missed is fully engaging that latch before powering on, which prevents the card from being recognised.

What drive-related maintenance will the 4-bay 3.5" SATA backplane require over time?

The backplane supports hot-swap SATA drives; plan to replace any failed drive by sliding it out and inserting a new 3.5" SATA unit without powering down the server.
